In California seismic design, a building located in San Francisco with Site Class D soil conditions would typically be assigned which Seismic Design Category?
Correct Answer
B) SDC E
CBC Chapter 16 and ASCE 7 seismic maps show San Francisco is in a very high seismic region. With Site Class D (stiff soil) conditions and the high ground motion values in San Francisco, buildings typically fall into Seismic Design Category E, requiring enhanced seismic design provisions.
